ROTARY GRAlN-MEASU RE.

SPECIFICATION forming part of Letters Patent No. 376,367, dated January10, 1888 (No model.)

To aZZ whom it may concern:

Be'it known'that we, JAMES E. BUSENBAR- RICK and GEORGE FyMrronnLt,citizens of the United States of America, residing at Robinson, in thecounty of Brown and State of Kansas, have invented certain new anduseful Improvements in Rotary Grain-Measures, of

which the following is a specification, reference being had therein tothe accompanying drawings.

This invention pertains to cerlain new and useful improvements in rotarygrainmeasures, the same having reference more particularly to that classof measures employed in connection with thrashingmachines, whereby thegrain is conveyed from the mouth of the thrasher during the thrashingoperation.

The object of the invention is to provide -simple and efficient meansfor securing to a common shaft preferably four grain measures orvessels, the same being arranged to operate 1 v automatically at themoment each measure or vessel is filled; and a further object is toproing mounted upon or in close connection to a thrashing-n1achine(notshown) at a point near the delivery-spout a, as shown. At about thecenter of this frame are secured, upon the upper surface thereof, two shortposts, a, designed to support at their upper ends the end of ahorizontal shaft or beam, B.

From the shaft B project four pairs of arms, B B, the same being rigidlysecured to said shaft, and between their outer projecting ends said armscarry or support measures or vessels B B B B*, as shown.

b b are short studs or projections rigidly secured or projecting fromthe sides of the meas: u re or vessel, and on these studs or projectionsare passed and rigidly secured at the outer ends of the arms B B,one ofsaid studs being projected or extended a short distance beyond the outersurface of each of said arms, as shown.

C is along bent lever fulcrumed at the point of conjunction of the armsd dthereof on the upper end of an inclined fulcrum-post, O, secured tothe top of the frame A. To the outer end of the short arm (1 of thelever G is secured a small roller or wheel, d,while to about the centerof the long arm dis secured a weight, D, the same being capable ofadjustment at the desired point by means of the series of aperturesdthrough any one of which is passed a nutted bolt, (1 projected throughsaid weight, as shown.

E E are two upwardly-projecting arms rigidly secured at their lower endsto the arms d d, respectively, of the lever O, a short distance oneither side of the fulcrum of said lever. The upper ends of these arms EE have secured thereto a curved plate, forming a cam, e, as shown.

To the lever O is secured, at the point of connection of the arm E wlthsaid lever, one end of an inclined lever,F,connected or jointed near itsforward end to the upper end of a second lever, f, pivotally securednear its upper end to the side of the frame A, and at its extreme outerend said lever is secured to or caused to encompass a dog, G. This dogGis loosely passed at its lower end through a keeper-plate, g, attachedto the lower end of the leverf, as shown,said dog being held.as againsttoo much movement downward, by means of a pin, g, passed transverselytherethrough.

To the dog G is secured one end of a spring, 9*, the other end beingsecured to the leverf, as shown. The upper end of this dog is bent atright angles. forming an arm, 9

H is a stiff spring rigidly secured at its lower end to the frame A atone end thereof, the upper end of said spring being bent, as shown.

It will be seen that there is but one measure or vessel in the properposition ready for re,- ception of grain at the same time, and thatmeasure or vessel, which may be of any de- ICC sired size or capacitysayone-half bushel- 1s nearest the spout a of the thrasher. While thismeasure or vessel B is being filled its stud or projection b is restingon the roller d of the lever C, said lever being held in the posltlonshown in full lines by reason of its own weight, together with theweight D, and when the weight of the grain falling into said measure orvessel equals or is sufiicient to counterbalance the said lever O andits weight D the same is instantly lowered, and by reason of itspressure on the roller d of the lever C the latter is caused to assumethe position shown in dotted lines, Fig. 1, the stud or projection b ofsaid measure or vessel being permitted to pass out beyond said roller ofthe lever, by reason of the length of the arms B being so much greaterthan the short arm of the lever O. Simultaneously with this movementofthe measure or vessel just filled the measure or vessel B,previously'below the frame A, moved in the direction of the arrow, andupon the rising of the long arm d of the lever O the same pulled on thelever F, causing the lever fand dog G to assume the position shown indotted lines in Fig. 1. Consequently when the measure or vessel Breached the position par-,

allel with the frame A the further movement thereof was prevented byreason of the stud or projection b coming in contact with the arm g" ofsaid dog, thus preventing the continued revolution of the measures orvessels by reason of the velocity acquired in the movement described.When the lever 0 reaches the position shown in dotted lines, Fig. 1, soas to permit the stud b of the vessel B to swing clear of the roller ofsaid lever, the cam 0 will be in the position also shown in Fig. 1, andupon release of the said stud said cam will begin to resume the positionshown in full lines, Fig. 1, the consequence of which will be thatimmediately upon such movement of, the cam the stud or pin b of thevessel B will collide with said cam, whereby said measure or vessel isslightly retarded in its movement, so as to prevent its momentum fromcarrying it be yond the roller d, with which it will come in contact.Immediately upon the completion of this operation, the measure or vesselB having reached the lowermost position, the lever C returns to itsnormal position, withdrawing the arm 9 of the dog G from contact withthe stud or projection 11 of the measure or vessel and the contact ofthe roller d with the stud or projection of the measure or vessel to befilled, said latter measure or vessel being held as against reversemovement by means of the spring H, the upper end thereof being incontact with the flanged rim of said measure or vessel, as shown.

It is obvious, of course, that the grain, upon falling from the measureor vessel in the descent ofthe latter, can be caused to enter a conveyeror other suitable device for removing the same.

If desired, any ordinary tallying device can be employed in connectionwith our invention to record the measuring of the grain, the same beingoperated in any known manner or by any preferred means.

We claim as our invention- 1. The series of measures or vessels havingtheir arms connected to a common shaft and provided with studs orprojections, and the lcvcrhaving a roller secured at one end, againstwhich bears one of said studs or projections of each measure or vessel,substantially as shmvn and described.

2. The series of measures or vessels connected to a common shaft andhaving studs or projections, the lever carrying a roller at one end, andthe dog havinga bent arm and operated through the agency of said lever,substantially as shown and described.

3. The combination, with the measures or vessels having the studs orprojections, and the carrying-arms connected to the common shaft, of thelever, the roller secured at one end thereof, the weight, thejointedlever connected to said former lever, and the dog, substantially asshown and described.

4. The combination, with the series of measures or vessels, of the leverhaving one end in contact with a stud or projection of one of saidmeasures or vessels, the jointed lever, the dog having abent arm, andthe spring connected to said dog, substantially as shown and described.

5. The combination, with the series of measures or vessels, of the leverhaving one endin contact with one of said measures or vessels, thejointed lever, the dog, and the cam supported by arms connected to saidlever, substantially as shown and described.

In testimony whereof we afiix our signatures in presence of twowitnesses.
